Question

我正在我的页脚上工作，我搞砸了某些地方并制作了一些东西，所以右边的屏幕上有一个空白区域可以滚动到。我该如何删除？这是我的代码。

The more intense the activity, the more calories you burn. You don't need to set aside large chunks of time for exercise to reap weight-loss benefits. If you can't do an actual workout, get more active throughout the day in simple ways — by taking the stairs instead of the elevator or revving up your household chores.</p></div>

Answer 1

向内容div添加容器类。在引导程序中，行需要位于容器类中。

<div class="content container"> <-- add container class here
    <div class="row">
        <div class="col-md-3 col-md-offset-2 ing"><img src="img/Ingraham.png"></div>
        <div class="col-md-6"><p class="content-text">....</p></div>
    </div>
</div>

编辑：

再次检查一下，你的内容类正在弄乱容器边距，所以最好这样做。

<div class="content"> 
    <div class="container"><-- add container class here
       <div class="row">
          <div class="col-md-3 col-md-offset-2 ing"><img src="img/Ingraham.png"></div>
          <div class="col-md-6"><p class="content-text">....</p></div>
       </div>
    </div>
</div>
